The New York Korea Center

The NY Korea center is a perfect example of challenging foundation construction in a tight urban environment. The site challenges include the tight layout, proximity to Amtrack tunnels, ground water influence, and the depth of the excavation. The project includes SOE drilling (both drilled with temporary and permanent casings), structural caisson drilling, underpinning (with maximum depths approaching 25 feet), drilled rock anchors, and cast-in-place foundation concrete. Excavation includes both soil and rock removals at depths exceeding 35 feet below street level.

Scope of work:

• Drilled HP14x102 SOE piles within 10’ of active Amtrack tunnels supported by multilift raker and heelblock system
• Drilled 13” SOE pipe piles supported by channel and hollow bar tieback system
• Drilled 15” caissons with isolation casing
• Drilled DCP tie down rock anchors, 6” diameter hole
• Underpinning pits ranging from 10-25 feet deep supported with multilevel hollow bar tieback system
• 30 foot plus excavation including soil and rock removals
• 25’ High Exterior Foundation Walls
• Concrete Caps, Footings, slabs, grade beams, etc.
• Dewatering
• Grace Waterproofing System
